[0002] The tobacco flavoring machine is a device for adding flavoring to tobacco products in the tobacco manufacturing process, which releases the flavoring and uniformly adheres it to the tobacco products, so that the fragrance of the tobacco products meets the corresponding requirements.

[0003] The commonly used tobacco flavoring machine usually adopts an external moisture removal mode, that is, the gas mixed with ash in the tobacco flavoring machine is extracted to a moisture removal well through a moisture removal pipeline. However, in the actual production process, the liquid material sprayed by the nozzle is in a mist state, most of which is absorbed by the tobacco material, and a small part is suspended in the air with the ash and is extracted to the moisture removal well, thereby causing a certain proportion of the flavoring to be unable to be completely applied to the tobacco material, resulting in deviation of the actual application ratio and loss of the liquid material. SUMMARY

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0049] In the following description, the terms "first", "second", etc. are only for the purpose of description, and cannot be understood as indicating or implying relative importance. The following description provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B and C, and another embodiment includes features B and D, the present application should also be considered to include one or more embodiments of all other possible combinations of A, B, C and D, although the embodiment may not be explicitly described in the following content.

[0050] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes can be made to the functions and arrangements of the described elements without departing from the scope of the present application. Various processes or components can be appropriately omitted, replaced or added in each example. For example, the described methods can be executed in different order from the described order, and various steps can be added, omitted or combined. In addition, features described with respect to some examples can be combined into other examples.

[0051] Referring to Figure 1 , Figure 1 The overall flowchart of the internal circulation and moisture removal method for the tobacco flavoring machine is shown.

[0052] As Figure 1 shown, the internal circulation and moisture removal method for the tobacco flavoring machine can at least include the following steps:

[0053] Step 102, when it is detected that the tobacco flavoring machine is in a running state, the first air pressure value of the rear chamber is collected by the negative pressure detection device, and the control state of the cyclone dust collector is determined based on all historical air pressure values corresponding to the rear chamber and the first air pressure value.

[0054] Before introducing one or more embodiments of the present application, please refer to Figure 2 The structural diagram of the external moisture removal equipment of the tobacco flavoring machine is shown. As Figure 2 shown, the external moisture removal equipment of the tobacco flavoring machine can include a tobacco flavoring machine, a moisture removal pipeline, a centrifugal fan, and a moisture removal well. The moisture removal pipeline can be used to connect the upper part of the rear chamber of the tobacco flavoring machine and the moisture removal well, and the centrifugal fan arranged on the moisture removal pipeline can directly extract the gas mixed with ash in the rear chamber to the moisture removal well through the upper part of the rear chamber, and in the process of extracting the gas, the tobacco material that has absorbed the flavor can be discharged from the discharge port below the rear chamber. It can be understood that the gas mixed with ash in the rear chamber can be extracted to the rear chamber by the moisture removal fan arranged in the tobacco flavoring machine, so as to avoid the tobacco material that has absorbed the flavor mixed with ash.

[0055] In actual production, since the material liquid sprayed by the nozzle is in mist form, most of the mist-shaped flavor is absorbed by the tobacco material, and a small part of the mist-shaped flavor is suspended in the air together with the ash and is extracted to the moisture removal well, thereby causing a certain proportion of the flavor to not be completely applied to the tobacco material, resulting in deviation of the actual application ratio and loss of the material liquid.

[0056] In the embodiment of the present application, the internal circulation and moisture removal method for the tobacco flavoring machine can be applied to, but not limited to, a control terminal. The control terminal can control and process the moisture removal architecture of the tobacco flavoring machine to realize the circulation flow of the material liquid gas in the tobacco flavoring machine, which not only can guarantee that the flavor is completely applied to the tobacco material in proportion, but also can improve the looseness of the tobacco material by using the circulation flow of the gas, thereby improving the overall flavoring effect of the tobacco material.

[0057] The tobacco flavoring machine exhaust structure can at least include a tobacco flavoring machine, an exhaust pipeline arranged between a front chamber and a rear chamber of the tobacco flavoring machine, a negative pressure detection device arranged at a discharge port of the rear chamber, a cyclone dust collector, a first valve and a centrifugal fan arranged in sequence on the exhaust pipeline. The inlet end of the exhaust pipeline can be connected with the upper portion of the rear chamber of the tobacco flavoring machine (or can be connected with a pipeline arranged in the rear chamber of the tobacco flavoring machine), so as to avoid extracting the cut tobacco material from the rear chamber, and the outlet end of the exhaust pipeline can be connected with the material inlet of the front chamber of the tobacco flavoring machine, so as to loosen the cut tobacco material conveyed to the material inlet of the front chamber and improve the overall flavoring effect of the cut tobacco material. The negative pressure detection device can be but is not limited to a negative pressure sensor, which is used to detect the gas pressure discharged to the rear chamber, so as to avoid problems such as that the cut tobacco material cannot be discharged. The cyclone dust collector can be arranged on the exhaust pipeline through a gas input end and a top output end, so as to obtain the liquid-gas mixture discharged from the upper portion of the rear chamber through the gas input end and discharge the liquid-gas mixture after dust removal to the exhaust pipeline through the top output end. It can be understood that the bottom output end of the cyclone dust collector can also be but is not limited to connected with a dust removal pipeline, so as to discharge the soot to the dust removal room for centralized treatment through the dust removal pipeline. The first valve can be but is not limited to an electromagnetic valve, which is used to open or block the exhaust pipeline according to the electric signal sent by the control terminal, and the first valve can be arranged in the exhaust pipeline connected with the top output end of the cyclone dust collector.

[0058] It should be noted that when the control terminal controls the above-mentioned tobacco flavoring machine exhaust structure, the cyclone dust collector can be used to remove the dust from the liquid-gas mixture discharged from the rear chamber, so as to avoid discharging the soot into the tobacco flavoring machine again, and the first valve and the centrifugal fan can be used to discharge the liquid-gas mixture after treatment to the front chamber through the exhaust pipeline, so as to realize the circulation of the liquid-gas mixture in the tobacco flavoring machine.

[0059] Specifically, when the tobacco flavoring machine is subjected to the exhaust treatment, the control terminal can but is not limited to acquire the working state of the tobacco flavoring machine at a preset time interval, and when it is detected that the tobacco flavoring machine is in a running state, it indicates that the tobacco flavoring machine has subjected the cut tobacco material to the flavoring treatment, and then the negative pressure detection device can be used to detect the gas pressure in the rear chamber, so as to determine whether the negative pressure in the tobacco flavoring machine is normal according to the first pressure value detected, that is, whether the cut tobacco material after the flavoring treatment can be normally discharged to the rear chamber. The tobacco flavoring machine can also be in a standby state or a stop state, and when the tobacco flavoring machine is in the standby state or the stop state, it indicates that the tobacco flavoring machine has not subjected the cut tobacco material to the flavoring treatment, and then the working state of the tobacco flavoring machine can be continuously acquired at the preset time interval.

[0060] Further, after obtaining the first air pressure value of the rear chamber, the control terminal can further, but not limited to, determine whether the first air pressure value is in the normal air pressure interval according to all historical air pressure values corresponding to the rear chamber when the tobacco flavoring machine is in normal operation, and further determine the control state of the cyclone dust collector, that is, further determine whether the cyclone dust collector needs to perform dust removal treatment on the gas discharged from the rear chamber.

[0061] As an option of the embodiment of the present application, determining the control state of the cyclone dust collector based on all historical air pressure values corresponding to the rear chamber and the first air pressure value includes:

[0062] performing mean value calculation processing on all historical air pressure values corresponding to the rear chamber, and obtaining a first difference value between the mean value result and the first air pressure value;

[0063] when the first difference value is in the preset difference value interval, determining that the control state of the cyclone dust collector is the running state;

[0064] when the first difference value is not in the preset difference value interval, determining that the control state of the cyclone dust collector is the stop state.

[0065] Specifically, when determining the control state of the cyclone dust collector, the control terminal can further, but not limited to, perform mean value calculation on all historical air pressure values corresponding to the rear chamber when the tobacco flavoring machine is in normal operation, and perform difference value calculation on the mean value result and the first air pressure value to obtain a corresponding first difference value. It can be understood that when the first difference value is in the preset difference value interval, it indicates that the air pressure of the rear chamber of the tobacco flavoring machine at this time is in the normal air pressure interval, which can effectively guarantee the normal discharge of the cut tobacco material, and with the normal discharge of the cut tobacco material, there will be a mixture gas of the cut tobacco material mixed with ash and misty flavor in the rear chamber, and then it can be determined that the control state of the cyclone dust collector is the running state, that is, the mixture gas of the cut tobacco material discharged from the rear chamber can be treated by the cyclone dust collector.

[0066] It can also be understood that if the first difference value is not in the preset difference value interval, it indicates that the tobacco flavoring machine at this time can be in the just running state, and there is no cut tobacco material discharged to the rear chamber after being treated by flavoring, and at this time, there is no mixture gas of the cut tobacco material mixed with ash and misty flavor in the rear chamber, and then it can be determined that the control state of the cyclone dust collector is the stop state.

[0067] Of course, a corresponding standard air pressure interval can also be determined by all historical air pressure values corresponding to the rear chamber when the tobacco flavoring machine is in normal operation, so as to directly determine the control state of the cyclone dust collector according to whether the first air pressure value is in the standard air pressure interval, and the present application is not limited thereto.

[0068] Step 104, when the control state of the cyclone dust collector is in the running state, the cyclone dust collector is controlled to perform dust removal treatment on the material liquid mixed gas discharged by the rear chamber, and when it is identified that there is soot in the material liquid mixed gas, the first valve is controlled to be in the on state.

[0069] Specifically, after determining that the control state of the cyclone dust collector is in the running state, the control terminal can but not limited to send a control signal representing running to the cyclone dust collector, so that the cyclone dust collector performs dust removal treatment on the material liquid mixed gas discharged by the rear chamber after receiving the corresponding control signal, and when it is identified that there is soot in the material liquid mixed gas, it is indicated that the existing soot has been separated from the material liquid mixed gas, and then the first valve can be controlled to be in the on state, that is, the treated material liquid mixed gas is discharged into the moisture removal pipeline where the first valve is located. It should be noted that since the soot in the material liquid mixed gas cannot be directly and effectively and quickly identified, it can only be effectively determined that there is soot in the material liquid mixed gas when the soot in the material liquid mixed gas is separated, that is, when it is identified that there is soot in the material liquid mixed gas, the operation of separating the soot from the material liquid mixed gas has been completed.

[0070] Possibly, when it is not identified that there is soot in the material liquid mixed gas, it is indicated that there may be a pipeline blockage of the cyclone dust collector, and then the control terminal can but not limited to continuously identify whether there is soot in the material liquid mixed gas within a specified time period. If it is still not identified that there is soot in the material liquid mixed gas within the specified time period, a warning signal can be sent by the control terminal to remind the staff to check and process the cyclone dust collector.

[0071] As another alternative of the embodiment of the present application, the tobacco flavoring machine moisture removal architecture further comprises a dust removal pipeline connected with the cyclone dust collector;

[0072] Before identifying that there is soot in the material liquid mixed gas, further comprising:

[0073] acquire a pipeline image corresponding to the dust removal pipeline at a preset time interval, and perform feature recognition processing on each pipeline image;

[0074] When the similarity between the contour feature identified in any one of the pipeline images and the preset soot contour feature exceeds a preset similarity threshold, it is determined that there is soot in the material liquid mixed gas;

[0075] When the similarity between the contour feature identified in any one of the pipeline images and the preset soot contour feature does not exceed the preset similarity threshold, it is determined that there is no soot in the material liquid mixed gas.

[0076] Specifically, when judging whether there is soot in the slurry mixed gas, the control terminal can further but not limited to set a precision shooting device in the dust removal pipeline, obtain a pipeline image for viewing whether there is soot in the dust removal pipeline according to a preset time interval, and can perform feature recognition processing on each pipeline image to identify the object contour feature in each pipeline image. Here, one end of the dust removal pipeline can be connected with the bottom output end of the cyclone dust collector, and the other end can be connected with the dust removal room to concentrate the soot for processing.

[0077] Then, after identifying the object contour feature in any one pipeline image, similarity calculation processing can be performed on the object contour feature and the preset soot contour feature, and when the similarity result exceeds the preset similarity threshold, it indicates that there is soot in the dust removal pipeline at this time, and then it can be identified that there is soot in the slurry mixed gas. Possibly, when the similarity result does not exceed the preset similarity threshold, it indicates that there is no soot in the dust removal pipeline at this time, and then it can be temporarily identified that there is no soot in the slurry mixed gas. It can be understood that the similarity calculation processing mode can be a conventional processing mode, which will not be described in detail here.

[0078] Step 106, when it is detected that the first valve is in the on state, the centrifugal fan is controlled to be in the running state to make the treated slurry mixed gas pass through the moisture removal pipeline and be discharged into the front chamber.

[0079] Specifically, after controlling the first valve to be in the on state, in order to effectively improve the circulation efficiency of the slurry mixed gas, the control terminal can but not limited to control the centrifugal fan to be in the running state, that is, the treated slurry mixed gas is quickly discharged from the first valve through the moisture removal pipeline and discharged to the front chamber inlet of the tobacco flavoring machine by the centrifugal fan, which not only utilizes the treated slurry mixed gas to loosen the tobacco material in the front chamber, but also facilitates the adsorption of the mixed mist flavor on the tobacco material in the front chamber.

[0080] It can be understood that after the treated slurry mixed gas is treated in the front chamber, it can continue to be discharged to the rear chamber by the moisture removal fan arranged in the tobacco flavoring machine, thereby realizing the circulation flow of the slurry mixed gas in the tobacco flavoring machine, which not only guarantees that the flavor is completely applied to the tobacco material in proportion, but also utilizes the circulation flow of the gas to improve the looseness of the tobacco material, thereby improving the overall flavoring effect of the tobacco material.

[0081] As another optional embodiment of the present application, the tobacco flavoring machine moisture removal architecture further includes a second valve arranged on the moisture removal pipeline, and an angular actuator for controlling the second valve, the second valve being between the centrifugal fan and the front chamber.

[0082] After controlling the centrifugal fan to be in the running state, further comprising:

[0083] determine a first opening degree of the second valve based on a historical control signal of the angular actuator;

[0084] collect, by the negative pressure detection device, a second air pressure value of the rear chamber, and when detecting that a second difference between the second air pressure value and the mean value result is not in a preset difference interval, generate a target control signal corresponding to a second opening degree based on the second difference and the first opening degree;

[0085] send the target control signal to the angular actuator, so that the angular actuator controls the opening degree of the second valve to be the second opening degree.

[0086] Specifically, after controlling the centrifugal fan to be in the running state and realizing the circulating flow of the mixed gas of the material liquid in the tobacco flavoring machine, in order to avoid the mixed gas of the material liquid circulating into the front chamber affecting the stable air pressure in the tobacco flavoring machine, and thus failing to guarantee the smooth discharge of the cut tobacco material in the rear chamber, the control terminal can also but not limited to determine a first opening degree of the second valve corresponding to the last running state based on the historical control signal of the angular actuator, for example, by querying the control signal corresponding to the latest time in the historical control signal, and determining the first opening degree based on the control signal corresponding to the latest time. It can be understood that the control signal sent by the control terminal to the angular actuator can be used to control the angular actuator to control the opening degree of the second valve to be the opening degree corresponding to the control signal, that is, to adjust the rate of the mixed gas of the material liquid circulating into the front chamber.

[0087] Then, after determining the first opening degree of the second valve, the control terminal can also control the negative pressure detection device to collect the second air pressure value of the rear chamber, and when detecting that the second difference between the second air pressure value and the above-mentioned mean value result is not in the preset difference interval, it indicates that the mixed gas of the material liquid circulating into the front chamber through the second valve has affected the stable air pressure in the tobacco flavoring machine, and thus can but not limited to query an adjusted opening degree corresponding to the second difference in the preset air pressure difference-opening degree list, and determine a corresponding second opening degree according to the adjusted opening degree and the first opening degree. It can be understood that when the second difference is a negative value, the adjusted opening degree and the first opening degree can but not limited to be summed to obtain the second opening degree; when the second difference is a positive value, the first opening degree and the adjusted opening degree can but not limited to be subtracted to obtain the second opening degree.

[0088] Then, after determining the second opening degree of the second valve, the control terminal can generate a control signal corresponding to the second opening degree, and send the control signal to the angular actuator, so that the angular actuator controls the opening degree of the second valve to be the second opening degree.

[0089] As another optional of the embodiment of the present application, the moisture exhaust structure of the tobacco flavoring machine further comprises an adjusting air baffle arranged on the moisture exhaust pipeline, the adjusting air baffle is between the second valve and the front chamber;

[0090] After the target control signal is sent to the angle actuator, further comprising:

[0091] Based on the preset opening-rotation angle list, the target rotation angle corresponding to the second opening is determined, and the angle control signal corresponding to the target rotation angle is sent to the adjusting air baffle, so that the air baffle rotation angle of the adjusting air baffle is consistent with the target rotation angle.

[0092] Specifically, in order to improve the loosening effect of the tobacco material, the control terminal can further but not limited to, after sending the target control signal to the angle actuator to control the opening of the second valve to the second opening by the angle actuator, based on the preset opening-rotation angle list, the target rotation angle corresponding to the second opening is queried, the rotation angle here can be understood as the angle formed by the air baffle structure of the adjusting air baffle and the front chamber inlet, and the angle control signal corresponding to the target rotation angle can be sent to the adjusting air baffle, so that the air baffle rotation angle of the adjusting air baffle is consistent with the target rotation angle, thereby realizing the direction adjustment of the material liquid mixture discharged into the front chamber inlet. Not only can improve the loosening effect of the tobacco material, but also can further ensure that the tobacco material absorbs the misty flavor more uniformly and fully.

[0093] As another optional of the embodiment of the present application, the moisture exhaust structure of the tobacco flavoring machine further comprises a third valve arranged in the dust removal pipeline and a cleaning nozzle arranged at the top of the cyclone dust collector;

[0094] After the centrifugal fan is controlled to be in the running state, further comprising:

[0095] When it is detected that the tobacco flavoring machine is in the stop state, the cyclone dust collector is controlled to stop the dust removal process, and the cleaning nozzle is controlled to clean the cyclone dust collector;
